Outlook

Energy experts anticipate that 2004, like every year before it, will be remarkable for how much energy Americans waste. But if energy prices climb as high as predicted, consumers are likely to pay more attention than usual to the opportunities to be more efficient, and retailers expect the results to show up at cash registers.

The nation’s reliance on foreign oil has fallen sharply since 2005, when imports made up 60 percent of the liquid fuel used. A surge of new domestic production and a decline in consumption has transformed the United States’ energy outlook.
